Grstasports water bottle

I love the drinking flow of this bottle and the simplicity of the design; however - as a few people have previously reported - the leakproof is subpar. When on its side and transported in a bag that's not always upright, it frequently leaks from where the top part is screwed on (not from the top flap). We're slightly puzzled that this has not been designed better.

Great bottle for 2 days, the in the third pressed the little button to open lid spring open in its own without much force due to tiny spring, as lid flipped open it snapped off at the hinge, possibly poor design who knows, will see how long the other 2 last that was ordered at the same time 😤😤😤
